A Simple Algorithm for Closed-Loop Control of Stepping Motors
Stepping motors are normally operated without feedback and may suffer from loss of synchronization. This can be prevented by the use of positional feedback. A simple control algorithm is developed which allows a stepping motor to operate effectively in open-loop mode as long as it remains synchronized, but which recovers from loss of synchronization following a disturbance. The control algorith...
متن کاملDesign a Guidance Law Considering Approximation of Missile Control Loop Dynamics Using Adaptive Back-Stepping Theory
In this paper, a new guidance law is designed to improve the performance of a homing missiles guidance system in terminal phase. For this purpose first of all, the two dimensions equations of motion are formulated, then the approximation dynamic of missile control loop is added to these equations which are nonlinear whit unmatched uncertainty. Then, a new adaptive back-stepping method is develo...

متن کاملDOF Closed - loop Control for Planar Linear Motors
Planar linear motors (Sawyer motors) have been used in industry as open-loop stepping motors, but their robustness and versatility has been limited. Using a sensor recently integrated into such a motor, a closed-loop 3-DOF controller has been implemented. The software-based control system consists of a commutator for computing ampli er currents from actuator forces, a force resolution function ...
